Conformable therapeutic shield for vision and pain
First Claim
1. A method of treating an eye of a patient, the eye comprising a cornea having an ablated stroma, an epithelium and a sclera, the ablated stroma having an ablated profile, the method comprising:
- providing an unflexed covering comprising;
an inner portion having an inner modulus and at least one inner radius of curvature; and
an outer portion having an outer modulus and at least one outer radius of curvature;
wherein the inner modulus is greater than the outer modulus;
applying the covering against the eye so that the covering flexes with the inner portion providing a chamber between a posterior surface of the inner portion and the cornea in a region of the ablated stroma, and the outer portion engaging the cornea; and
resisting movement of the inner portion relative to the cornea using the engagement of the outer portion and the cornea.

Abstract
A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10-4 Pa*m3 to about 5×10-4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.

14. A covering for an eye of a patient, the eye comprising a cornea having an ablated stroma, an unablated stroma, an epithelium, and a sclera, the covering comprising:
-
an inner portion having an inner modulus and at least one inner radius of curvature; and an outer portion having an outer modulus and at least one outer radius of curvature; wherein the inner modulus is greater than the outer modulus; and wherein the covering, when applied to the eye, is configured to flex with the inner portion providing a chamber between a posterior surface of the inner and the cornea in a region of the ablated stroma and the covering is configured to resist movement of the inner portion relative to the cornea. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of treating an eye of a patient, the eye comprising a cornea having an ablated stroma, an epithelium and a sclera, the ablated stroma having an ablated profile, the method comprising:
-
providing an unflexed covering comprising; an inner portion having an inner modulus and at least one inner radius of curvature, wherein the at least one inner radius of curvature comprises a radius of curvature less than a radius of curvature of the ablated stroma, wherein the inner portion comprises a substantially uniform thickness; and an outer portion having an outer modulus and at least one outer radius of curvature; wherein the inner modulus is greater than the outer modulus; applying the covering against the eye so that the covering flexes, with the inner portion at least partially conforming to the cornea, providing a chamber between a posterior surface of the inner portion and the cornea in a region of the ablated stroma, and of; and resisting movement relative to the cornea using the engagement of the outer portion and the cornea.
